Each has its place. I know it may not be possible in all places, but the best way I've found to avoid fawns is to provide better fawning cover elsewhere in the plan. We have plots that are planted for summer and then again for fall and others that are perennial plots. I use WR/PTT/CC in my fall mix. So, it the spring, the WR becomes the early spring food followed by the CC. I cam mow the WR in April well before fawns drop. This releases the CC and makes the field unattractive for fawning. I then plant our summer mix in late May or early June. Our perennial clover plots look like weed fields all summer long unless you get down and look under the weeds. Except for the first spring after a fall plant with a WR nurse crop when I mow the WR the following spring each time needed to keep release the perennial clover, I never mow these in the spring. The summer weeds, many of which are quality food for deer, dominate during the summer but also help to shade the clover reducing its dormancy. I mow them once a year in the fall, when our fall rains become more frequent and nights cool down favoring the clover over summer weeds. The clover rebounds quickly and dominates the fields over the season and following spring.
I have never hit a fawn yet using this approach. That said, I realize that everyone has different limitations on time and technique depending on region and situation and not everyone can do this.
Thanks,
